By adopting the sheet-shaped resistance formed by direct punch of metal sheet as basic resistance unit, the utility model doesn't generate the sense volume, thus a series of problems brought by the winding resistance are readily solved; the utility model has much smaller volume than the winding resistance, which has remarkable advantages of large capacity current, fast heat dissipation, and higher reliability; the utility model can be widely used in the fields of motor staring and braking and grounding resistance, and has irreplaceable advantages.
Description
Technical field
The utility model relates to a kind of metallic resistance control cubicle, particularly a kind of Metal Flake resistance control cubicle that is widely used in fields such as electric motor starting brake field and earth resistance.
Background technology
High speed development along with transportation industry, popularizing of subway, electric locomotive, track traffic magnetic suspension train, reliability, stability, thermal diffusivity, life-span and sensibility reciprocal to brake resistance require to increase, original wire resistors etc. can not be satisfied the demand, its major defect is that volume is bigger, sensibility reciprocal is big, and noise is bigger, and radiating effect is undesirable.
The utility model content
The purpose of this utility model provide a kind of volume little, hold that galvanization is big, the Metal Flake resistance control cubicle of rapid heat dissipation, reliability height, zero sensibility reciprocal.
The purpose of this utility model is achieved in that a kind of Metal Flake resistance control cubicle, comprises cabinet, it is characterized in that: two booms are housed in the cabinet at least, and the two ends of boom are fixed on the cabinet, are with insulating sleeve on the boom; On a boom, be set with pellet resistance, conductive tube, porcelain tube successively, and it is a plurality of to repeat suit by this order; On another boom, be set with pellet resistance, porcelain tube, conductive tube successively, and it is a plurality of to repeat suit by this order; It is fastening as a whole by nut that the pellet resistance outer end at two ends adds porcelain pad insulation back on each boom; On two booms, form a snakelike rotating pellet resistance series circuit thus by a plurality of pellet resistances connect by conductive tube and porcelain tube insulation isolation is formed; And connect lead wire by the pellet resistance at two ends, draw lead by lead wire again and connect external circuits.
The purpose of this utility model can also following manner realize: pellet resistance is made up of resistor disc, insulating barrier and card article; Resistor disc has card article in the checkpost up and down, has the insulating barrier insulation to isolate between card article and the resistor disc.
Insulating barrier is a mica paper.
The netted resistor disc that resistor disc forms for the snakelike revolution resistor disc that formed by bar hole or by mesh or be the resistor disc of the two mixing shape that has concurrently.
The insulating sleeve that is with on the boom is a micanite pipe.
Cabinet is made up of framework, side plate and wire netting; Side plate is equipped with in the both sides of framework, and wire netting is equipped with in the forward and backward and bottom surface of cabinet.
The utlity model has following advantage: because the pellet resistance that adopts on sheet metal directly punching press to form is done basic resistance unit, do not produce sensibility reciprocal, so a series of problem of being brought by wire resistor is readily solved.Have the volume littler than wire resistor, and big, the rapid heat dissipation of appearance galvanization, the remarkable advantage that reliability is higher.
